The FLM‑420‑I8R1‑S Octo-input Interface Module with Relay allows the monitoring of up to eight inputs.
Additionally, it features a change‑over contact relay for providing a potential‑free output contact. The FLM‑420‑I8R1‑S Octo‑input Interface Moduleprovides two monitoring functions: Monitoring of a line by an EOL resistor, monitoring of a potential‑free contact. FLM‑420‑I8R1‑S allow for a seperate connection single external element.
